By definition, Newton's First Law, also called the Law of inertia, indicates that "Every body perseveres in its state of rest or of uniform rectilinear motion unless it is forced to change its state by forces impressed on it."

This means that for a body to come out of its state of rest or of uniform rectilinear motion, it is necessary for a force to act on it.

<h3>Definition of inertia</h3>

So, in other words, all bodies are opposed to changing their state of rest or motion and this opposition is called inertia.

<h3>Body in equilibrium</h3>

In this way, a body is in equilibrium when the resultant of the forces acting on it is zero. That is, it is not possible for a body to change its initial state (be it rest or motion) unless one or more forces intervene.

At a waterpark, sleds with riders are sent along a slippery, horizontal surface by the release of a large, compressed spring. Th

steposvetlana [31]

The sleds speed when the spring returns toits uncompressed length is v = 0.03 m/s.

<u>Explanation</u>:

Given,

force constant = 42 N/cm = 0.42 N/m, mass m = 68 kg, spring x = 0.39 m

The potential energy, U, stored in the spring is

U = 1/2 kx^2

= 1 / 2 $\times$ 0.42 $\times$ (0.39)^2

= 0.032 J

All its potential energy has been converted into kinetic energy since it has a uncompressed length.

K = 1/2 mv^2

v = sqrt (2K / m)

= √(( 2 $\times$ 0.032) / 68)

v = 0.03 m/s .

The field inside a charged parallel-plate capacitor is __________.

Bess [88]

<span>Uniform. A parallel plate capacitor is a simple arrangement of electrodes and dielectric to form a capacitor. Here two parallel conductive plates are used as electrodes with a medium or dielectric in between them. Charge separation in a parallel-plate capacitor causes an internal electric field, which is uniform.</span>

Answer:

At a distance of 1376.49 candle emits 0.2 watt power

Explanation:

Distance between Sun and earth $6.6\times 10^{16}m$

Sun emits a power of $P=3.8\times 10^{26}watt$

Power emitted by candle = 0.20 watt

We know that brightness is given by

$B=\frac{P}{4\pi d^2}$

So $\frac{3.8\times 10^{26}}{4\pi (6\times 10^{16})^2}=\frac{0.20}{4\pi d^2}$

$3.8\times 10^{26}d^2=7.2\times 10^{32}$

$d^2=1.89\times 10^6$

$d=1376.49m$

So at a distance of 1376.49 candle emits 0.2 watt power

grigory [225]

<span>The answer is transformer. They utilize electromagnetic induction to generate current. This is only possible in alternating current due to the differential increase and decrease of electrical current that induces changes in magnetic flux in the coil. This varies the magnetic flux of the primary coil that generates current in the secondary coil.</span>
